Well, the original Canon MTFs are already soso at 24mm.

I reckon we'll now see Photozone MTFs are are a bit closer to what Canon is providing.

Focus shift ... isn't helping ...

I'm beginning to suspect that the lens is defective.

Then TDP also had a defective unit?

I've a hard time to believe that the lens is that bad.

I can see a certain centering issue specifically at 105mm but it's not too bad by normal standards.

The outer field is worse than on the mk 1 there.

So at photographyblog the results are as bad (interpolated from their 5D IV results).

<div>Ok, I'm rolling back the review of the Canon EF 24-105mm f/4 USM L IS II. Centering defect - although I think there's more to it (IS group ? I hate image stabilizers ...).

Between this and DPReview's *ahem* less than enthusiastic review of the Sigma 12-24 Art, looks like the testing business has not been all roses and candy lately...
